I guess I should have made it clear that I believed the Elodea helped
specifically with the BGA, rather that all algae. Possibly, once the
bacterial infection was gone, the tank could reach a balance more favorable
to the higher order plants.
Not being an expert in this field (which is why I read the list in the
first place), I rely on the expertise of others. I first picked up on this
idea from the list. I went looking for confirmation, and found a reliable
source that did. Thus, from the Tropica website;
Egeria densa is a good plant for beginners, and its rapid growth helps
create a balance in the aquarium from the start. It can also help prevent
algae because it absorbs a great number of nutrients from the water. The
plant secretes antibiotic substances which can help prevent blue-green
algae (a type of bacteria). The growth rate depends largely on the amount
of light and nutrition available. Growth does not stop in unfavourable
conditions, but the plant turns light in colour and the tendrils grow thin.
Being one to let sleeping dogs lie, I believe I will leave the plants in
place, at least for a while. If it wasn't the reason the BGA went away, the
scourge will probably return anyway.

that took care of the problem.
> at first congratulation for your succes! For clarification: elodea is a
synonym. What do you mean, Egeria densa or Lagarosiphon major? Sorry, but I
don't believe, that was "elodea". I have both of the plants in my tank and
I don't see any effect against algae, which are present. I think, something
else, of course I cannot tell you what, won the fight over algae. Make a
test: Remove "elodea" for a time and see what happens. I think, algea will
_not_ come back. In any case, be happy! Regards, Klaus.
